Question

atomic radius is measured as half the distance between the nuclei of two bonded atoms of the same element when linked by single covalent bond.
by measuring by this method we can also get the wrong measurement as some elements cannot bond by single covalent bond like O2

Answer 1

Hello friend!!!

This way of calculating atomic radius is applicable preferably for single bonded spicies and not much for double bonded species.

This is because

◆More attraction between the nucleus and the 2 shared pair of electron

◆Repulsion between the 2 shared pair of electrons.

◆Repulsion between the shared pair electrons and the electrons of constituent atoms.

◆Repulsion between the nucleus of the constituent atoms.

◆Attraction between the nucleus of one atom of the constituent atoms and the electron cloud of the other.
